, Vises, oi' which the following is a Speccation.

This invention relates to quick. acting vises and has for its object to provide in a lvise improved means .for rapidity in connecting the operating mechanism with kthe moving jaw, and also improved means for operating the moving jaw at a throw or the lever, -in either direction.

lV ith these and other objects in view the device comprises certain novel constructions, combinations and arrangements of parts as will be hereinafter more fully described and claimed.

Referring to the accompanying drawings which are made a part hereof, and on which similar reference characters indicate similar parts,

The improved vise which forms the subject matter of this application comprises a base 15 of substantiallyl the usual and ordinary type adapted to be secured to a bench or other fixed object in the usual manner by inserting bolts through the ears 16. Upon this base 15 a `disk 17 is mounted for limited Specification of Letters Patent.

Serial No. 314,225.

rotary movement to change the angular Aposition of the work operated upon by the vise, no novelty, however, residing in this ad- `justment, it beine: old in this class of implements.

Upon the disk 17 a housing 18 is erectedy providing space for the passage therethrough of the beam 19 of the movable jaw 20. Upon each side the beam 19 has countersunk therein a rack plate 21 and through the beam and the rack plates 21 a slot 22 is provided vfor the purpose hereinafter described.

Within the housing 1S clutch members 23 are located having teeth 24 positioned and proportioned to engage the teeth of the rack bar 21. The end of' the clutch member adjacent the teeth 24 is drilled to receive a spring 25 and a slot 2G is provided to receive the inclined or cam extremity 27 ot the spring k2S, such cam extremity bearing against the spring 25 so that there is double spring action provided by 4the springs 25 and the springs 28. ,kreferably, though, not necessarily, these clutch members 23 with their accompanying springs 25 and 28 are located upon opposite sides of the beam 19. Such use of two clutch members insures equality of action and avoids binding of the parts. '1`he ends of the clutch members 23 opposite the teeth 24 bear against cams 29 formed integral with the shaft 30 which at its extremities is provided with multi-angular portions 31 to receive a lever 32 which may be placed upon either end of the shaft 30 as occasion may make desirable. r1`he slot 22 in the beam 19 is properly proportioned to permitthe passage therethrough of' theushatt 30 so tha' in assembling the device the clutch members may first be inserted in the housing and the beam 19 inserted through the housing by means of the hand hold 33 and the shaft inserted transversely through its bearings and through the slot 22 of the beam. The clutch members 23 are now permitted under the action of their springs 25 and 28 to move slidably against the cams 29 and by reason of the shoulders adjacent such cams, prevent the removal of the shaft 30 until the contact between the clutch members23 and the cams is again released.

After assembling the device, as just hereinbefore described, the operation is as follows. The lever 32 is raised to a vertical Patented June 29, 1920.

position, as shown in full lines at Fig. l, whereby the shaft 30 is rotated so that the major of the cams 29 also stand vertical. In this position the springs 25 and 28 force the clutch members 23 outwardly away from the rack 2l permitting the free movement of the jaw 20 and beam 19. This is accomplished by manipulating the jaw through engagement with the hand hold 33 closing the movable jaw into engagement with theA work. The movement of the lever 32 in either direction to or toward the dotted line position shown at Fig. l irst rotates the shaft 30 and the cams 29 forcing the clutch members 23 in a direction away from the axis of the shaft 30. By reason of the inclined slot 26 the cam extremity 2' and curvature of the spring 28, the movement of the clutch member 223 is translated into a transverse movement toward and into engagement with the teeth of the rack 2l. T he continued movement of the lever forces the clutch members a still farther distance in position to the spring 28, but being now in locked engagement with the beam i9, moves the beam 19 and movable jaw therewith. By reason of the formation of the cams 29 the device will remain in any position to which the lever 2has been moved, retaining the work securely clamped between the jaws until the lever is returned to vertical whereupon th'e parts being again disconnected by the action of the springs 25 and 28 the work is released by the manual movement of the sliding jaw. This completes a cycle of operation and the device is in condition for repeating on any kind or size of work.

llaving thus fully described my said invention, what l claim as new and desire to secure by Letters Patent, is: y

l. ln a. vise, a housing, a jaw beam having` spaced teeth along its side inserted through the housing, a clutch member positioned within the housing and having teeth proportioned to coact with the teeth of the beam, means to hold the clutch member normally and yieldingly with the teeth out of engagement, a cam adapted when oscillated in either directionto move the clutch into engagement with the teeth ofthe beam and to further move the beam after such engagement, and means to apply power to the cam.

2. A vise comprising a housing, a jaw beam freely movable within the housing, a ri ck formed upon the side of the jaw beam, a clutch member disposed within the housing and having teeth proportioned to interen'gage with the teeth of the rack, a spring tending to move the clutch out of engagement with the rack, a cam adapted when os cillated `in either direction to move the clutch against the tension of spring into engagement with the rack and to provide for a further movement of the engaged beam, and means to`apply power to the cam.
